Intelligent robots are leading a new round of technological revolution and industrial transformation. Promoting the intelligent robot core chip technology and industry is strategically significant for industrial upgrading and productivity improvement in China. In this study, we illustrate the strategic significance of the intelligent robot core chip technology in China in promoting technological independence, realizing high-quality economic development, satisfying residents’ need for a better life, and promoting a nation’s core competitiveness. Additionally, we review the development status of chips for intelligent robots in terms of policy, technology, and industry, and analyze the advantages and problems of developing intelligent robot chips in China. On this basis, the development route of intelligent robot chips is analyzed, and the development strategic goals of intelligent robot chip technology for 2025, 2030, and 2035 are proposed. Moreover, we propose the key tasks and strategic goals of intelligent robot core chips in China. We suggest that the independent and controllable development of intelligent robot chips should be elevated to a national strategy; major scientific and technological projects should be established for intelligent robot chips; policies should be introduced to encourage intelligent robot chip technology research and industrial applications; and high-level talent training should be implemented.

Purpose: This study was aimed to develop frequently-used clinical scenarios and scoring rubrics to assess core basic nursing skills in adult health nursing clinical practice for clinical evaluation based on program learning outcomes (PO). Methods: This study was a methodological research combining focus group interviews and questionnaires to select and construct scenarios. Data were collected from clinical practitioners, adult health nursing professors, and new nurses from November, 2013 to April, 2014. The developed scenarios and rubrics were applied to nursing students by way of showing an example. Results: The 12 frequently-used clinical scenarios were developed. The proportion of the evaluation rubrics were 30% for clinical instructors where as 70% for college instructors. In order for students to achieve the important learning outcomes from the courses for clinical practice, four program outcomes (POs) were selected as well as a rubric for each POs was developed. Students who had situation-based clinical practices showed higher levels of satisfaction on mastery of core basic nursing skills and communication skills. Conclusion: This findings of the study suggested the strategies for complementing pitfalls in clinical setting and achieving PO during students’ clinical practicum. [ABSTRACT FROM AUTHOR]

Centipede-like robot, which has high degree of freedom and similar body segments, proposes new requirements on real-time control for diverse gaits. To meet above requests, we have studied the movement characteristics of multi-legged creatures and found the features of gait periodic relay. Then the instruction-relay control scheme, the three-bus control system and its software algorithms were designed. In our experiments, with the designed control system, different gaits of robot could be switched flexibly and the phase difference between body sections could be changed by altering relay time. As a whole, this control system could accomplish the requested control task and reasonably simplify the gait control algorithms and procedures. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the human health risks (premature death risk as an indicator) in Beijing, Shanghai, Guangzhou and Xi'an during extreme haze in January 2013., Methods: The daily average particulate matter ≤ 2.5 µm in aerodynamic diameter (PM2.5) concentrations of Beijing, Shanghai, Guangzhou and Xi'an in January 2013 were collected and their characteristics explored. The populations and mortality rate of four cities in 2010 were collected from the statistical yearbook, the exposure-response relationships selected from the reference and then the premature death calculated according to the proportion risk model of Poisson regression., Results: In January 2013, the 24 h mean concentrations of PM2.5 in Beijing, Shanghai, Guangzhou and Xi'an were (240 ± 165) , (83 ± 27), (94 ± 49) and (210 ± 98) µg/m(3) respectively and they were all above the secondary level of Ambient Air Quality Standards (GB 3095-2012). The 24 h mean concentrations of PM2.5 in Beijing and Xi'an were much higher than those in Shanghai and Guangzhou. Approximately 86.4% (19/22) , 58.1% (18/31), 54.8% (17/31) and 93.5% (29/31) of 24 h mean PM2.5 concentrations in Beijing, Shanghai, Guangzhou and Xi'an respectively exceeded the secondary level of Ambient Air Quality Standards (GB 3095-2012). The number of premature death due to the exposure to haze were 725 (95%CI: 457-977) for Beijing, 296 (95%CI: 96-502) for Shanghai, 310 (95%CI: 189-434) for Guangzhou and 85 (95%CI: 21-141) for Xi'an respectively in January 2013., Conclusion: The PM2.5 pollutions of four cities in January 2013 were serious enough to pose elevated risks of human health.
